Adafruit APDS9960 -AND/OR sensor

Support
1

Hi there,

I’ve got this rascal blu-tacked up by my desk:

I can get it to recognise gestures, and record light/colours, but not seemingly at the same time

If I put the gesture first, then it will happily pick that up, but stop reading colours

, or if I put the colour reading up, then it will do that, but not recognise any gestures. I’ve tried having them in separate files, that wipes out the colours too. If it keep the “apds.color_data_ready” part in the loop, then everything stops, or if I take it, then the values never change

is it either/or, or am I missing something. I thought about going multithreaded, communicating between the processes with queues, but there’s limits

Has anyone managed to do the 2 simultaneously?

thanks

Toby

Yeah that’s an odd one, with a quick play about I’ve been able to experience the same thing: colour readings work fine until the first gesture, when everything seems to lock up.

There were some bug reports about this sensor locking but maybe they didn’t realise the extent of it.
